|12/16/11 Update: Home made collimation setup further results -
After aligning using the brightest spot in my test images below such that it did not move while rotating the camera, I still had a uniform tilt to my CCD
Inspector results. I suspected that if I lessened the angle between the laser and the CCD (made it more perpendicular), it might be better. It did and I now
have a perfectly collimated camera. I moved the pen such that it almost eliminated the angle while still allowing the beam to pass to the side of the pen and
onto a projection wall some 4 feet away. Projecting onto a wall provides more accuracy than the roofing shingle did. Good luck!
|Original Angle - beam to
CCD surface -
Results. Could be just
luck and not the angle -
but I do think CCD
inspector works well
based on just looking at
how the image brightned
|20 second image of
Messier 35. Tak 106 fsq
at prime. No changes to
focus or setup between
pictures. Only one
image was taken with
collimation (other than a
wrong exposure in
between) and the 2nd
results were achieved on
the first try (colltest3).

original 'all wood'
|The objective is to get the CCD surface spot to center when
the camera is spun. Below is my current collimation rig with
my 60Da doing 4 second exposure while I spun the camera.
Collimation is almost perfect (images right) I think or I would
see 3 circles in the center.
